IDENTIFICATION
A. Infrared Absorption
B. Thin-Layer Chromatographic Identification Test
To pass the test.
Acceptance criteria: The RF of the principal spot of the Sample solution corresponds to that of Standard solution A.
Residue on Ignition: NMT 0.1%
Limit of Lead:
To pass the test.
Acceptance criteria: NMT 0.5 micro-g/g
Barium:
Standard solution: Add 6 mL of water to 5 mL of the Sample solution prepared for the Acidity test.
Sample solution: Add 5 mL of water and 1 mL of dilute sulfuric acid to 5 mL of the Sample solution prepared for the Acidity test. Allow to stand for 1 h.
Acceptance criteria: Any opalescence in the Sample solution is not more intense than that in the Standard solution.
Appearance of Solution:
To pass the test.
Acceptance criteria: The Sample solution is not more intensely colored than the Control solution.
Microbial Enumeration Tests and Tests for Specified Microorganisms: The total aerobic microbial count does not exceed 103 cfu/g, and the total combined molds and yeasts count does not exceed 102 cfu/g.
